Several days of prescription medication and doctor’s note in case of arrest.

Menstrual pads, if needed. Avoid using tampons ¡V if you’re arrested you may not have a chance to change it (tampons left in for more than six hours increase your risk of developing toxic shock syndrome)

What not to do:

Don’t put Vaseline, mineral oil, oil-based sunscreen or moisturisers on skin as they can trap chemicals.
